I give you an example for this problem. Hope it helps.

    DropDownChoice dropDown = new DropDownChoice(...........);
    AjaxFormComponentUpdatingBehavior behavior = new AjaxFormComponentUpdatingBehavior(
                            "onchange") {

                @Override
            protected void onUpdate(AjaxRequestTarget target) {
                  //you should write here the logic that
               // replaces the panel, something like: content.addOrReplace(panel)

                target.addComponent(form);
            }
    };
    dropDown.add(behavior);

So that's all, you have to use AjaxFormComponentUpdatingBehavior to handle onchange event. If the dropdown menu not a requirement, you can use tabbedpanel. Here you can find the sample code: wicket tabbed panel
